Objective To evaluate outcomes of endovascular procedures for atherosclerosis obliterans (ASO) patients with diabetes mellitus (DM).Methods Data of patients undergoing endovascular procedures for atherosclerosis obliterans at the First Affiliated Hospital of Anhui Medical University from January 2012 to December 2014 were retrospectively analyzed,disease characteristics,technical success rate,perioperative complications,ankle brachial index (ABI) improvement,clinical success rate,rest pain alleviating rate,limb salvage rate and survival rate were compared between the two groups.Results There were 144 patients (153 limbs) who received endovascular procedures,including 52 patients (56 limbs) with DM and 92 patients (97 limbs) without DM.Mean follow-up was 15 months.All patients experienced significant ABI improvement (P ＜ 0.05).There was no significant difference in technical success rate (80.4％ vs 90.7％),perioperative complications rate(19.6％ vs 24.7％),1 year rest pain alleviating rate (75.0％ vs 85.6％),1 year limb salvage rate (91.1％ vs 95.6％) and 1 year survival rate (92.3％ vs 90.2％) between diabetic and non-diabetic groups (P ＞ 0.05),but there was less 1 year clinical success rate in diabetic group (78.6％ vs 88.6％,P ＜ 0.05).Conclusions Compared to nondiabetic paitents,endovascular procedures for patients with DM has similar efficacy,when the procedures are properly undertaken and postoperative correct medication are given.
